Can you extend PS or LR application across to the iPad so palettes and tools are on the iPad? Can the 11" iPP (or iPad Air) work well in portrait for this, or is the 13" iPP a better combination in either landscape or portrait? Even if you have a larger MBP, what are your experiences using an iPad as a second screen, specifically with Adobe apps? I'm mainly considering PS, LR, XD, and Animate.
